String.fromCharCode won't work with a variable?

    When I use String.fromCharCode to directly convert Unicode values to characters it works.

    THIS WORKS
    
alert(String.fromCharCode(104,116,116,112,58,47,47,119,119,119,46,103,111,111,103,108,101,46,99,111,109));
    Code (markup):
    But if I want to put the Unicode values in a variable, then convert the variable to characters, it doesn't work.

    THIS DOESN'T WORK

    
var mylink="104,116,116,112,58,47,47,119,119,119,46,103,111,111,103,108,101,46,99,111,109";
alert(String.fromCharCode(mylink));
    Code (markup):
    Why? How can I make String.fromCharCode work with a variable?

    Jan has the solution. Basically, you entered text into a function that only reads numbers.

    Thanks Jan, tested and working :D

    I spent about an hour trying to solve it. I knew the problem had something do to with String.fromCharCode only accepting numbers, but just couldn't get anything working.
